Direct Coupling Blast Wheel for different shot blasting machines in dust layer removal

After years of research and development and technical cooperation with German companies, the company has produced a high-power direct-coupled shaft 7.5-75Kw high-efficiency shot blasting machine, breaking the European and American high-power direct-connection shot blasting technology monopoly. This shot blasting machine is the highest-end technology in Asia and is a key component of various shot blasting equipment. It is widely used for sand falling of castings, surface cleaning of castings, forgings, welded parts, heat-treated parts, and surface pretreatment of various profiles. Processing, and surface strengthening process of gears, springs and other mechanical parts. This direct-shaft shot blasting technology is one of the important advances in the development history of China's shot blasting equipment. The shot blasting machine also has the following characteristics:

Advantage

It has the advantages of compact structure, convenient maintenance, low noise, low consumption, high efficiency, etc.: the direct connection technology eliminates intermediate transmission losses and removes many wearing parts-belts, pulleys, spindles, shaft seats, etc., reducing maintenance work the amount. In addition, it occupies a small area and is flexible in layout, which is easy to meet the layout of the projectile belt. It also has overall replacement performance and easy maintenance.

Compound projection belt: In order to completely clean the yin and yang, convex and concave surfaces of the workpiece, the shot blasting blade has a wider projection area, and the width of the horizontal projection belt is 1.5~2 times that of the conventional shot blasting machine.

Structure: Compared with the old belt blast wheel, the shot blasting speed is constant, there is no uneven cleaning or strengthening effect caused by belt slippage, and the cleaning quality will not fluctuate. The efficiency of this shot blasting machine is as high as 20kg/min•kW, and the energy consumption is 20% lower than that of the ordinary shot blasting machine.

Material and technology: long working life of wearing parts: The wear parts of this blast wheel are made of Cr28% high chromium wear-resistant cast iron melt film precision casting, and the service life is more than 3 times that of tidal sand castings. The manganese steel shells of all blast wheel are processed by a large gantry CNC milling machine at one time;

Blast wheel impeller: The impeller body is carburized with wear-resistant alloy. The impeller body is processed at one time by a high-precision CNC machining center with high precision. Compared with other simple processes, it has obvious advantages, ensuring the balance of high-speed operation, low vibration, low noise, and long life;

The double discs in the shot blaster are riveted into one body to form the impeller body. The impeller body is equipped with eight blades, and the impeller body and the blasting wheel at the center of the shot blasting wheel are installed on the main shaft driven by the motor. The cover is lined with a protective plate, and the cover is equipped with a directional sleeve and a pill inlet tube. When working, the projectile flows into the blasting device from the blasting pipe. The splitting wheel that rotates synchronously with the blade makes the projectile get the initial velocity. The projectile flies out through the window of the directional sleeve, and is thrown onto the high-speed rotating blade outside the directional sleeve. After being further accelerated by the blade, the projectile is thrown onto the surface of the workpiece to be cleaned. Because the split pill wheel and the blade rotate synchronously to ensure the vibration-free transmission of the projectile to the blade, thereby reducing the wear on the blade.
